It wouldn't be D&D without the basics. The first few classes they need to add would be ranger, paladin, bard, monk, and druid. As long as they have one decent version of each of these classes they will have the main classes most people look for in D&D. Personally I think they need to do away with having multiple versions…
#1 - the kung fu stance is annoying and makes no sense out of combat. #2 - give some other implement options. I hate the orb and would much prefer a staff or even wand #3 - give some fire attacks #4 - more defensive spells #5 - maybe throw in some illusion magic
Yes, Yes! A millions times yes! Please for the love of the gods get rid of the two finger stance. That and bring the wizard a decent implement. What kind of wizard can't use a staff or wand?! I know it is only my opinion but the sole use of the orb just ruined my favorite class...
